<p><span style="color:#696969">A French user</span>, <a href="https://www.facebook.com/pennyass/posts/10153838748026422">Penny Powell</a>, <span style="color:#696969">posted images to Facebook last month showing what looks like a build up of mould in the two-piece valve.</span></p>

<p><span style="color:#696969">This part of the bottle cannot be opened to be cleaned and, under certain conditions&nbsp;can lead to a build up dirt and possibly bacteria.</span></p>

<p><span style="color:#696969">Since the issue was reported, Tommee Tippee have been quick to respond with a statement in which they sincerely apologised to any parents who have been affected by the mould issue.</span></p>

<p><span style="color:#696969"><em>&quot;The company will be launching a new Sippee cup in the next few months, which will have a two piece valve that can be used with different types of liquid and is easier to clean.</em></span></p>

<p><span style="color:#696969"><em>The statement added: &quot;In the meantime, we are making transparent, see-through valves immediately available to any parents that have concerns.</em></span></p>

<p><span style="color:#696969"><em>&quot;The see-through valve will enable parents to see inside and give them confidence that the valve is clean, when used in line with recommended instructions.</em></span></p>

<p><span style="color:#696969"><em>&quot;If you would like to receive a see-through valve or alternative cup please contact our Careline on free phone 0808 206 8000, and one will be sent as quickly as possible.</em></span></p>
